Microsoft have announced a new end of life date for their Enhanced Mitigation Experience Toolkit (EMET). Version 5.5 will now be supported until 31st July 2018. After this date there will be no support or patching for EMET, and the official advice is to switch to Windows 10. Where EMET is currently used with Windows 10 it will also not be supported as of that date.
